I have a PC desktop which has a motherboard with some expanded capacitors and needs to be replaced. I think it is an atx, but don't know how to identify the manufacturer in order to replace it. Can anyone help? Thanks

atx has 20 pin connector (2x10) where power supply connects to motherboard

there must be some markings on board to identify manufacturer, at least some numbers if not a name. get out magnifying glass and google the numbers you find

First, is there a manufacturer or is this a "White Box" as they call them. If is a major manufacturer, it should have a model number.

If it is a white box, open the case and look for any identifying marks. They are usually screen-printed on the board in White. Sometimes near the CPU and sometimes between a couple of PCI slots.

Any info can be googled and may bring us back the correct info.

OR, you can download SWI.exe and run that. It will list your motherboard manufacturer. It is available here:


or Everest, available here:


Good luck.

If this is a non-working computer and you cannot find the info anywhere, sometimes you can trace it through the FCC number printed on the board and looking it up here:

Thanks for the replies
This computer was built by a local computer company who is now out of business. It has an AMD64 processor running at 1.8 MHZ. I am pretty sure it is an Atx. It has a P1 power connector, 2 - 184p ram slots, a cpu socket 7 (I think) with fan on top. The MB measures approx 8" x 8". There are several numbers and letters, but the only thing that looks like a manufacturer is: CE FC next to the modem board. Also there is a sticker with "QC17" over a FQC logo close to the processor.

ATX is now a industry form factor, with the motherboard this pertains layout including the rear connectors.

If you have decent soldering skills you can remove the caps and take them to you local electronics shop and they should be able to provide you with replacement caps. Use a pencil soldering iron, not a soldering gun. When you remove the caps pay attention to the polarity, this article shows the most common ways of identifying the polartiy. The motherboard will also have indications of the polarity, usually either a + or half of the silkscreened section under the cap will be a solid color indicating the positive lead.
